DESCRIPTION:The vast majority of viruses infecting humans, animals and plants\npackage their genomic material into protein containers that are organised\naccording to icosahedral symmetry. The structure, formation and strategies\nof infection of these viruses can therefore be understood in terms of group\ntheoretical tools. We have introduced and classified affine extensions of\nnon-crystallographic Coxeter groups to predict details of virus\narchitecture, including the dimensions and characteristic structural\nfeatures of the protein containers and the organisation of the genomic\nmaterial within. In this talk, these new mathematical tools will be\nintroduced and their predictive power for virus architecture demonstrated\nbased on a number of test viruses. It will then be demonstrated that these\nmathematical insights shed new light on how viruses form and infect their\nhosts.
